| Abstract: |
A colon catheter for removing and collecting waste colon material through the anal canal. One end of a hollow tube is inserted into the anal canal and held therein by an expandable member and limiting elements outside of the anal opening against the perineum. An enclosed bag attached to the end of the tube to collect waste colon material may be made of plastic, may be clear and may be covered by an opaque bag having a viewing window and flaps to enclose the hollow tube after use. A side opening may be provided for introducing an enema solution. The entire colon catheter with the enclosed waste colon material is disposable as a unit.

First Claim:
Show all 26 claims |
I claim:
1. A catheter for removing waste material from the colon through the anal opening comprising:
- an elongated hollow tube having a first open end and a second open end, and a lumen through the tube from the first open end to the second open end being of circular cross-section having a diameter of at least 10mm to facilitate the passage of solid waste colon material from the first end thereof to the second end thereof,
- a pair of limiting elements attached to the outside of the said hollow tube between the first and second ends and extending outwardly in opposite directions from each other generally perpendicular to the axis of the tube to lie against the perinean force and aft of the anal opening,
- said tube including a first portion between the first open end and the limiting elements which includes the first end and which is insertable into the anal opening, and a second portion from the limiting elements to the second open end, said first portion being of sufficiently stiff material to withstand the inward closing force of the anal sphincter muscles,
- an annular expandable member fixed to and encircling the exterior of the first portion of the tube from said first end to a point along the exterior of the first portion of the tube and constructed to be expanded outwardly to surround the exterior of the tube at the said first end to seal off the anal canal such that waste material can escape from the colon only into the first open end of the hollow tube, and therethrough to the second open end, said expandable member, when expanded extending outwardly from the first open end transversely relative to the axis of the tube to assist in guiding waste colon material into the said first open end, passage means for delivering pressurized fluid to the annular member to expand it after it is positioned in the anal canal,
- the spacing along the exterior of the tube between the limiting elements and the expandable member being such that after the first portion of the tube has been inserted into the anal opening, the anal canal is sealed between the limiting elements and the annular expandable member to retain the first portion of the hollow tube in place and seal the anal opening,
- and means for connecting the second open end of the tube to an enclosed container such that waste colon material can flow from the colon through the first open end and through the lumen of the hollow tube directly into the enclosed container.
